WebThis method is particularly suitable for manual conversion from an arbitrary radix r to radix 10, given the relative ease with which we can perform radix-10 arithmetic. To perform the radix conversion using arithmetic in the old radix r, we repeatedly divide the number x by the new radix R, keeping track of the remainder in each step.

The Trachtenberg system is a system of rapid mental calculation. The system consists of a number of readily memorized operations that allow one to perform arithmetic computations very quickly. It was developed by the Ukrainian engineer Jakow Trachtenberg in order to keep his mind occupied while being in a Nazi concentration camp. The rest of this article presents some methods devised by Trachtenberg. Some of the algorithm…
